Time Out says
You’ve got two options with Theresa: the relaxed and trendy Grill, serving hunky waiters and succulent cutlets, rib-eye and chops, or the more glamorous, softly-lit and softly-furnished Bar Restaurant. The latter is great for romance with its pastoral murals, plush velvet seating, and a mouth-watering sharing menu. Whether you want to roll your sleeves up for the red meat, or dress up for smoked salmon tartar with beet mayo, both Theresa venues are the kind of places you want to savor flavors late into the night (though the Grill is also a great choice for lunch, particularly after a visit to the nearby Brandhorst Museum). Happily, the bar stays open until at least 1am.
